Objective data sheet
7.15.6.1 Features
7.15.7.1 Features
7.15.6 High-speed USB Host/Device/OTG interface (USB0)
7.15.7 High-speed USB Host/Device interface with ULPI (USB1)
Note: Synchronous static memory devices (synchronous burst mode) are not supported.
The USB OTG module allows the part to connect directly to a USB host such as a PC (in
device mode) or to a USB device in host mode.
The USB1 interface can operate as a full-speed USB host/device interface or can connect
to an external ULPI PHY for High-speed operation.

Four chip selects for synchronous memory and four chip selects for static memory
devices.
Power-saving modes dynamically control CKE and CLKOUT to SDRAMs.
Software-controlled dynamic memory self-refresh mode.
Controller supports 2048 (A0 to A10), 4096 (A0 to A11), and 8192 (A0 to A12) row
address synchronous memory parts corresponding to typical 512 MB, 256 MB, and
128 MB parts, with 4, 8, 16, or 32 data bits per device.
Separate reset domains allow auto-refresh through a chip reset if desired.
